Probabilistic Approach to Soil Fertility Conservation by Mathematical Modeling of Technological Processes and Optimization of Resource Use

The well-being of the state directly depends on food security. Many factors and indicators affect the stability of food security in the country. It consists of the availability and sufficiency in quantity and quality of food to each resident of the country. Therefore, the main goals of the economic and agricultural policy pursued in Russia are to provide the best and balanced solutions for producing more agricultural products that meet all domestic and foreign quality requirements. In the article, the authors consider the operation mode of a rice irrigation system from a probabilistic point of view. A model of the process of setting the price of planned activities for step-by-step price changes has been compiled. Each period of new planned activities is called a phase. It is assumed that events form a Poisson flow of constant intensity. At the n-th phase, a satisfactory state of the system occurs. The optimization problem of optimal assignment of the events price at each phase is solved and a numerical iterative algorithm for its solution is obtained.
